Pixie had a bad attack

Pixie just scared the hell out of me. I went to the bathroom, and he was just fine, following. When I got to the bathroom, I heard him whinning loudly. So I looked and there he was lying in the middle of the hallway, unable to get up, his eyes wide with fear. I didn't know what was wrong with me, so I ran to him, while tonz of all negative thoughts popped in my head. Either he was having a heart attack (although Whitty used to suffer them and he didn't behave like this) or something bad had happened to his body. I didn't know what though but whatever it was it was bad. The worst part was that mom wasn't home and I couldn't take dad's car if I needed to take him to the vet. I could grab Pixie and run down the street to the vet if needed be, but I didn't think I could make it on time to save his life. So I tried to make him stand up, but he couldn't balance himself. That's when I realized he was having an epileptic attack. I grabbed him and sat outside with him until it passed. The whole attacked lasted perhaps 10 seconds, but it felt more like 10 minutes. I was so scared, I started shaking badly. Gosh, I'm still shaky and hyperventilating.
